The loading time is TOO LONG

Two days ago, after I upgraded the client to the latest version, I noticed that the loading speed of each conversation had increased by several times compared to before.

Previously, it might take 1 minute to load a conversation, but now it takes an average of several minutes for each one. Even my largest conversation (a 55MB PB file), that conversation required A full 20 minutes to load.

Before the version update, there was no such problem.

Please fix the issue of long loading times. It is not necessary to download and load the entire conversation history from the beginning every time a conversation is opened. A more lightweight startup is needed.
